Common Symptoms
- Visible water leakage beneath or inside the dishwasher from a cracked, split, or poorly seated hose connection.
- Incomplete or slow draining when the hose is kinked, obstructed, or restricted.
- Standing water or drain-related error indications when drainage through the hose is impaired.
Check Before Replacing
- Disconnect electrical power before inspecting the hose or its connections.
- Inspect accessible hose routing for sharp bends, kinks, flattening, cracking, or evidence of rubbing.
- Check the hose connection areas for moisture or dried water residue after a drain operation, without assuming the hose is the confirmed cause.
- If safe access is available, check for a visible obstruction or restriction in the hose and confirm that the drain pump, filter, and downstream drain connection are not the actual source of the symptom.
- After service, run a short rinse or drain operation and observe both hose connections for leaks before fully reinstalling the dishwasher.
Pro Tip
Because 00645149 is the internal sump hose, do not substitute Bosch customer-facing external drain hose 00668108 for this application. Preserve the original hose routing and maintain the dishwasher drain connection's required high loop or air-gap arrangement.
